UNITED STATES PATENT OFFICE.

JOHN J. CONVERY, OF

AKRON, OHIO. ASSIGNOR TO THE GOODYEAR TIRE & RUBBER COMPANY, A CORPORATION OF OHIO.

TIREMAKING MACHINE.

Application filed July 27,

To all whom. it may oner-r21:

lle it known that I, JOHN J. Coxvunr, a citizen of the United States, residing at 'Ahron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in lire-h'laking Macl i i l ies, of which the following, is a specitiation, reference being had therein to the accompanying drawing.

This invention relates to tire-making machines and. more especially to machines for producing what is commonly known in the trade as the carcass of a pneumatic-tire shoe or casing. This carcass' comprises a plurality of superposed layers ol l'alnic (with or without clincher-howls embedded therein) having the general configuration ot the finished shoe.

In machines of this character. a rotatable lllt l tillll or core is generally (lll])l() \'ttl. and the carcass is formed around or upon the rotating core by rollers or other truth--- i vressing members manipulated to roll, Elmo or prcss a layer of tire-fabric upon th c then a layer is superposed upon that. :l tiually. one or more layers are ll1i0fv-t-ai upon the second layer and also folded around previmisty-inserted clincher-heads.

ln such machines. the desideratmn is to manipulate the fabric-pressing instrtunetrtalitios so that the successive la ers of riihl erin'ipregnated fabric will he properly positioned and shaped Without wrinkles or creases, and this can best be effected by proriding for the exertion oi a uniform pressure of the pressing-instruihentalit ies against the tire-fabric as the some is being shaped on the core. Uniformity of operation w salts in a practically unform and high- ;rrade product. i i

It is a feature of my in'i e'ntion to provide for such uniformity and, moreover. to presrnt a machine which, by reason of its sim' plicity of construction and conwznient ag- ,oronpment of parts, may be manipulated by a single operator. Efficiency and speed of operation are likewise features of the invention. Practical tests have demonstrated that, with a machine constructed in accordance with my invention, a carcass" ot superior character may he produced in a proximately half the time that is usually required for the purpose.

(hie object 01 the invention is to provide certain novel instrumentalities and inertia-- 1914. Serial No. 353 336,

nisms for auto: i:- tically opt-rating and controlling the actuation of the fabric-manipulating devices.

Another object is to provide means for accuratelr positioning the tabrie-i'nanipulating devices in relation to the tire-form or core and in predetermined relation to particular portions thereof.

Another oliject is to provide automatic means for piedeterminately arresting the actuation of such devices and, then, to etl'ect a return of the various operating instrumcntalities to normal position. 7

Anoth r object is to provide means for varying the extent, of movement of the parts or the period of their operation.

Another object is to provide means for ctlcctimg adjustments lIPI'B JY the relation of the lltllls ma be varied for different siZttl l'uoducts.

Supporting structure.

' The various devices and mechanisms, hereinafter demribed, are preferably siistamed by a general supporting-structure which includes a main frame 1, standards 2,

3, and 4', a top late 5, and tie-bars 8 and '10 connecting t e standards. The general form and dimensions of this may, of course, be varied.

. Driving mechanism.

Certain of the aforementioned devices preferably receive-motion from a common driving-mechanism sustained by the sup sorting-structure, and this includes a main riving-shaft 11 journaled' in suitable bean ings in the standards 3 and 4. 'On the shaft are mounted pulleys 12 (Fig; 1) by means of which it .may be driven from any suitable source of ower.

The main shaft 11 also carries a pinion 16 in mesh with a gear-wheel 20 that is fixed to a shaft 21journ1aled in bearings in the standards 2 and 3. Loosely mounted on the shaft 21 are a gear-wheel 22 and a pinion 23 which mesh with apinion 24 and a gearwheel 25, respectively, fixed on a shaft 26 which is ount to turn in bearings in the standards'2 and 3. S lined on the shaft 21 between gear-wheel 22 and pinion 23 is a suitable c utch-coll'ar 27 0 erated by a handlever'28 and adapted to thereby shifted into-engagementawith either the lllibOf the gear-wheel 22 or the hub of the pinion 23 to 'cause one or the other to be rotated by the shaft 21. Wher the clutch-collar 27 is enga ed with the gear-wheel.22, the shaft 26 wi 1, through the gear-wheel and the inion 24, be rotated at a comparativel higi rate of speed. When, however, the c utchcollar is engaged with the pinion 23, the shaft 26 will, through this pinion and the gear-wheel 25, be rotated at a. comparatively slow rate of speed.

Tireform or core.

The shaft 26 extends beyond the standard 2 and has secured thereto aliub 29 provided with radial arms 30 (Figs. 2 and 3) and constituting a form supporting structure. These arms carry an annular tire-Torin or core corresponding exterior-l r to the interior ofa pneumatic tire-shoe, the carcas of scribed, in relation to the tire-form.

Presser-supporting carriage and fabric-mm nz'pulatz'ng mechanism.

Juxtaposed to the tire-form and prel'en ably sustained by the main frame, is a carcass-forming structure which includes the following mechanisms and instrumentalitics: Secured to the tie-bar 8, or to any other appropriate portion of the main t'ran' e' is an outwardly-extemling bracket 32 'ivhich may, if desired, be formed asan integral part of the frame. The bracket is pi -ov1ded with an upper guiding and steadying l'li') 33 and a lower tack 34 for sustaining a presser-supporting and positioning carria e 35, this carriage being movable under the control of mechanism presently to he (ii best seen in Fig, 9,.the carriage is adapted for a sliding movement on the 1il;."anil provided with anti-friction rollers {16 \illi ll roll upon the track 34 to facilitate the travel of the carriage. If,'for any reason, it be desired tosecure the carriage to the guiding-rib 33, or to tighten it up to take up wear, the-screw 33 may be utilized. This bears against a wear-strip 33 Movement of the carriage on the steadying rib and track in 'relation to the tire form may be effected in any desired man ner; but I prefer to accomplish this by means of a threaded shaft or feedscrew 37 suitably journaled in the bracket The outer end of the feed-screw may be provided with a hand-wheel 38 by means of which it maybe turned in either direction. Means may also be provided for power-driving the screw: To this en d, it terminates adjacent to and in axial alinement with a'short shaft 39 mounted to turn in bearings 40 on the standard 2.

The shaft 39 is driven from the shaft 21 by a pair of bevel gear-wheels 41 and'42. The shaft 37 has a clutch-collar 43 splined thereon and adapted to be moved by a handlever 44, fulcrumed on the bracket 32, into and out of engagement Witha clutclrcollzir 45 fixed on the shaft 39, whereby when the collar 43 is moved into engagement with the collar 45, the feed-screw: 37 will be actuated by the power transmitted from the main shaft 11; and, when the collar 43 is disengaged from the collar 4.5, the feed-screw .will cease to rotate.

Any suitable means for connecting the carriage to and disconnecting the same from the feed-screw may be provided. For instance, in the embodiment herein illustrated by way of example, the screw 37 is engaged whereupon further by :a horizontally-split two-part clamp-nut =16 (Figs. 7 and 9), the upper and lower parts of which are slidably mounted in ways in the carriage 35 and are movable toward and from each other and into and from engagement with the screw. Each part of the clamp-nut provided with a projecting stud which carries a roller 47, and the rollers 47 are arranged in inclined slots 48 formed iii a hand-lever -19 which is fulerumcd at 50 (between the slots 48) on the carriage 35. This lever and its slots 48 are soar-ranged that when its upper cud is moved outwardly. the tam parts of the clampnut 46 will be moved away from each other and, thus, out of eugigemmit .with the screw 37 and, when sa l upper end is moved inwardly, the two pa. is of the uni will be moved toward each other and into engagement with the screw.

By this means. the carriage is advanced toward the tire-form, such advancing movcmcnt bring cii'cclcd in at least two ways, namely. manually. by turning the. hand wheel last on the foul-screw. zmd by power trausmilied'to the feed-screw through the gears, shafts. etc. from the main driving mechanism. It will thus be seen that bo h the core-supporting structure and the pre se1-su moi-ting carriage may be actuated by power and whereby their relation with respect to each other may be changed for purposes presently to be explained. The carriage may be given a receding movement to normal posituu by reversely rotating the 'i'c d-scrmv (when unconnected with the driving-nu-chanism) or by moving the carriage backward and away from the tireform 31 by haud. L 7

When the carriage 35 reaches a predetermined position in its advancing movement-- and which position may be varied in a manner presently to be describedit is desirable to provide for automatically arresting such movement and this may be accomplished, for instance, by disconnecting the carriage from the t ed-screw. are provided for automatically disconnecting the two-part. nut from the feed-screw, advance of the carriage stopped. For this purpose, I provide the following: li'voted at 51 to the top of the carriage 35 is an arm 52. the Tree end of which lies in, the path of n'iovement ot' the hand-lever 49 and adjacent the outer end of a roller on a block 53 which is slidable in suitable ways on the carriage lVheu the lever is moved inwardly to ettect engagement of the nut 46 with the screw 3T, it moves inwardly the arm 52 and therewith the block 53. After'tlie carriage 35 has been moved inwardlyby theiscrew.

As already explained, the carriage oiiects (in part) such a positioning of these fabric-manipulating devices either toward or away from the tire-form, mm:- "1;: to whether it is being-advanced twvnni the same, or moved away therefrom. "View fluid-pressure devices accomplish an lili'ilillfinlil posieioning of the rollers and, moreover, maintain them resiliently in context, or in contuoting relation, with the i'ehi'io-coverm'l form 31, The springs 67 ofi'eul; a receding movement of the pressingnemiiers 57 away from the form and are, thus, poewrroperated positioning-devices,

Sii.l'i-il!ill to and controlling t operation of ilioee prees'ure ilevices: To this end, the outer oml of each pneumatic cylinder 63 is bmmecied by n flexible ipe 68 to a pipe 69 \vl'f =h iemie'io the outfit-opening 70 1n an airw'nl've 7 i. This air-valve (as shown in F] 4 and 5) comprises a body-portion sewzr'wl to the hrecket 32 and a head. 72 re- .t y iliLliQ'Li in tho body-portion.

Leadmin the valve inlet-opening 76 is a "upeconnected to an air-supplying device and which nmintains a constant airorzv esm'o at the valve 71, SilCll devices for the purpose being common and well known. It will time be seen that when the arm 74 is; in the full-l 3 position, air will be suplied in the o inolsrre 63 to project the r0 lone. tomutl the tire-form 31 and against Means are provided for sup lying pres- )QlS 5'7 are, thus, pressurwperated and 7-; in the valve 71 when the arm the action of the springs 67, and the arm 74 is in the dotted-lino position, the air will be permitted to escape from the cylinders 63, whereupon the springs 6'? will draw the rollers 57 away from the tireform.

In a machine of this character. it is desirable to arrange for the operation ol the pressure-deviceswhich position the press er-members 57as aforeincntioncd in pre determined relation to the initiating and arresting of the advancing movements of the carriage: In the present instance, I avail myself of the operation of the hand-lever 49 (which controls the actuation oi the clamp-nut 46) to set the air-valve Tl There fore, the parts are preferably so related that, when the lever 19 is operated to tngragrc the clamp-nut with the feeds/crew 23? for setting the carriage in motion inwardly, the valve-arm 7i is moved to the i'ulLline position; and, when the carriage has travcled inwardly in its advancing nioienzent to a predetermined position. the val\'carin 74 will be automatically moved to the dot ted-line position, and for this purpose 1 provide the following: Pivoted to the lever 49 is a rod 79 (Figs. 3 and 7) fitted to slide through an aperture in an arm 80 llliFtlUitling from the bearing 40. This rod 79 carries a collar 81 (Figs. 6 and 7) to which is pivoted, at the upper end of a short a ia 83 which hangs normally in the l'olhl no position shown in Fig. 6. This asn 111a move on its pivot 82 to the tloltc l-line pi .:i tion shown in said figure. being prcvcntml from moving in the reverse direction by its stop-portion S i engaging the 81.

K'Ulltll' \Vhcn the lever 49 is in the position where the clamp-nut 46 is held out of engagement with the feed-screw 37, the collar 31 ocean ies a position between the air-mlva arm 4 and the lever 49, and said arm is in the dotted-line position shown in Fi 3. Therefore, when the lever 4-9 is moved to cited engagement of the clamp-nut 4G with the feed-screw, the rod 79 and its collar 91 are moved to the position shown in F 3, thereby causing the pivoted arm 85; to onage the valve-arm 7 1 and move it from the dotted-line position to the full-line position. The valvearm 74 then remains in this position. whereupon an oliset rod 8;) (projecting; from and n'ioving' with the carriage in the path of the arm Tl} one ages and automatically moves it back lo the dotted-line position. This not only closes the valve 7]. so that the air -supply is cut oil, .but, by opening the port 77 in the valve. per niits the air to escape lhcrcthro' gh and. thus, from the cylinders 63.. i" rally at the. same time. the handl r auto l c-ally moved in the opp. on

that when to disengage the clamp-nut. 46 from the feed-screw 37, as previously explained. As the lever 49 and the rod 79 and its collar 81 move outwardly, the pivoted arm 83 rides over the valve-arm 74 and drops down to the full-line position shown in Fig. 6 :for a succeeding operation.

llcreinabove, I have described how the fabric-pressing members are positioned in two different ways in relation to the tirefoinr. namely, by the peumatic or pressuredeviccs in projecting them toward and withdrawing them from the form, and by the carriage (during its advancing and reced ing; movements) in disposing them in and out of prliximity lo the form. It is desirable to provide additional means for effecting the'r further positioning at certain stages of the press ng operat on: and-this third method of positioning contemplates the changing oflhe degree oftheir angular relation to the surface of the form and, thus, to each other: To this end. cat-h bracket 59 is provided with a. doivcwardlv projecting pivot-stud 86 (Figs. 1;; which is mounted to turn in an auxil arr carriage .or presser-sustainin crosshcad 87. Each of the cross-heads S7 slidably mounted in guideways formed in a bracket or trunnion-member 88 supported by the carriage The pivot-stud S6 of each ln'aclret 59 carries a toothed whcci $29 which meshes with a rack 90 fixed to the adjacent wall of the bracket 88. In consequence. when the cross-head 87 is moved in its .goidcways. the wheel 8!) and therewith the bracket 59 will be turned on a verti al axis formed by the pivot-stud 86 to change the angle of the pressing-roller 57 relatively to the tire-form 31. To actuate the cros -heads and. tl1creby,'the pressingrollc s. OIH'li cross-hcad is connected by a l'lil (ii to an arm 92 splincd on a rocketshal t 93. This shaft is common to the two cross'diend connectingyrods and is journaled in bearing 94 adjacent the front edge of the brackets 88 and, also. in a bearin 95 on the carriage 35. \Vhen the vshat 93 is rocked, the crossheads 87 will we nzoaul in their guideways relatively to the lnaclwis and carriage Suchmoveincnt of the cross-heads in one direction bodily moves the pressing-members 57 along the surface of the tire-form and also rotates them on their vertical axes, whereby their pos'tion in relation to their initial contact with the form not only clmnged but their angular relation thereto is also changed. The instant of movement of the cross-heads is prede termiued and is controlled by instrumentalities presently to be explained.

For cliil'erent size tires, for instance, means are provided to vary the spaced relation of the pressing-rollers 57. and, this is accomthus, toward and from the planes of the sides of the form 31, one bracket 88 being located on one side of the plane alining with one side of the form 31 and the other bracket being located on the otherside of a plane alining with opposite side of the form To adjust the brackets 88 relatively, I provide a shaft 97 having a r'ght-hand screw-thread engaged with a block 98 on one bracket 88 and a left-hand screw-thread engaged with a block 98 on the other bracket. The

shaft 97 extends through an opening in awall 99 of the carriage and carries a hand-wheel 100 and collars engaging each side of the wall 90. When the wheel 100 5 is turned, the brackets 88 and, therewith; the

fabric-rollers 57 will be uniformly adjusted either toward or away from each other, in accordance with the direction of movement of the wheel 100.

The means already referred to for controlling the instant and extent of movement of the cross-heads 87 and, thus, of the fabricrollers 57 contemplates the following:

The rock-shaft 93 which governs the angles of these rollers is 11%; against turning durin a portion of the a vancing movement of the carr'age 35 and, then, during another portion of such movement of the carriage is caused to rotate, by a cam-block 101 (Figs. 3, 9, 20 and 21) supported onthe bracket and having a camway 102 therein in which is located a roller 103 carried by an arm 104 fixedtoand depending from the right-hand end of the rock-shaft 93.

i The cnmway 102 has a horizontal portion revent the turning 105 which. operates to of the rock-shaft 93 uring one sta of the travel of the carriage 35, and a d: we rdly extending end-portion 106 which permits the roller 103 to descend and efleot a rocking of the shaft 93 during another stage oi. the travel of the carriage. Pivoted to the side of the cam-block 101, as at 107- a hook-shaped arm 108 having'a corner which is adapted to be raised into enu c not with the roller 103 when it reaches iii; 'nddasl'i line position shown in Fig. 30, n .zlen the carriage is in movement, this arm 108. is raised by a plate 110 outstanding from the right-hand side of the carriage and engaging the bottom of a roller 111 on the arm when the roller 103 reaches the dot'and-dash line position. The purpose of zho arm 108 will be hereinafter explained fzont'al portion 105 msaa'ro inthe' de ription of the operation of the machine. $1

. For reasons recently to be explained, the.

cam-block 101 )8 adjustable. To this end, it is slidable longitudinall in a guideway 112 in the bracket 32 and, t us, has at least two v different andefiective positions: .In the po'-' sit-ion in' whichthe cam-block is shown in portions 105and 106,0f thecamway 102 one operation, 'as' will be hereinafter ex- "plained. In the other position (not shown) 'the drawinga'theroller 103 will travel both which thecam-bloek occupies when adjusted toward the axle of rotation of the'tire form 31, the roller 102-twill only traverse the horiof the camway 102 .for another operation, will also be hereinafter. explained.- To adjust the cam-block to either of,these two positions, I provide the following: Upstandfng from the bracket 32 is a plate 113 (Figsif21- and.22) having a horizontal slot 114 therein through which extends a stud-115 having a collar 116.'for engaging one face of the'plate' 113 and hav-' in a nut 117 for engaging the other face of said plate.

in the slot 114 and clamped carrying a square block a vertical gmdeway' 121 in the adjacent side The Stand 115 may be adjusted. longitudinally in positions oiadjustment by the nut.117.- v Pivoted on the stiid 115 is a hand-lever 118.

located within ock 101 in the;

same direction to. its second position of ad ijustment, .in can only traverse the horizontalgportion 105 o'f-the camway 102 during the travel of the carria 35.

These i-outcznplate cutting-devices for trimming the rough edges of ,the layers of fabric utter being rolled or shaped around the term 81. and embody the following strnrture: lCr-rh bracket 88 is provided with a dowmvanl extending stud 126 (Figs. 1.). us. 17 and 18) on which is pivoted a braclte 137 with a uideway128 formed therein. lidahlv titted to the guideway 128 is a cross-head or carriage 129. Extending" through the earriage 129 is a screw-threadcd spiudh 1 211 mounted to turn in a bearing in a wall 1:31 of the bracket- 127 and provided with a handle 132 by means of which it may he turned to adjust the eross-herul 129 Innertudinally of the bracket 127 and toward or from the axis of rotation of the form 311. Pivoted on the cross-head 129. by means of a stud 133, is-a bracket 13 adapted to turn about the axis of the stud 13S and to be held in positions of adjustment by a pair of screws 135 extending through pro tions 136 on the cross-head129 and engaging the respective sides of :1 lug 137 which extend from the bracket 134 to a position between the screws 135. This bracket is provided with a'pair of upwardlyextendinz: arms 138 between which is formed a guiding-slotfor the reception of a knife 132') having its inner or cutting-edge located adiaceui that. portion of the form 31 at which it is desired to trim the rough edges of the layers oil fabric. One end of the knife is secured (as by screws) to a block 1 1 which is pivoted to a hand-lever 141. said screws also serv ng as pivot-studs for the block. The lever 1411s fulerumed at 143 on the bracket 134 and-is adapted to he moved on such tulcrum to move the knife toward and from the form 31. The knife is not only guided.

by the slot formed between the arms but it is also guided by a pin 14 1 extendine' between e arms above the Knife and h an anti-llriction roller 145 below the knif and jonrnaled on a pin extending between the arms. The roller 14.3 takes the downward thrust on the knife 1539 caused by its ongagement with the fabric during the rota tion of the form 31. By adjusting the an riage 129 on the l acket 127. and by adjust- 11111 the braeket 131011 the carriage 129. the.

position and angle of the knife 139 with respect to the form 31 may be changed as desired. The bracket 127 is supported by a collar 146 fixed to the stud 126 beneath the bracket. The collar 116 has a tooth 147 adapted to engage a tooth 14.8 on the bracket .27 and prevent the turning of the bracket 127 on the stud 126 when pressure is applied to the hand-lever 141 during the cutting operation.

Before the fabric-rolling operation. the bracket 1317 and the parts carried thereby are removed from the cross-head 129 by withdrawing the stud 13;). and the braeket 127 may then be raised to disengage the tooth 115% from the tooth 1:17 and move outwardly on the stud 126 to a position where it will not intert'ere with the fabric during the rolling operation. After the rolling operation, these parts are positioned for the cutting operation. as already explained.

Operation.

The general ope ation ot the n'iaehine is as follows:

Figs. 10. 11 and 12 show. diagrannnatirally. the manner in which the layers or plies ot fabric an" the annular beads are placed upon the form 31 and also some of the ditterent positions which the fabrie-rollers {i7 assume during the rolling operation.

teiuent having been applied to the the form 31 in the usual mannera. strip of fabric forming the innermost layer or ply and supplied as from a stock-roller. such as R. Figs. 1 and 2, is stretched around the form, in the usual condition. The sides of strip proiec t, from the form. as indicated at (lin Fig. 10. \Vhen the layers are being: applied to the form 31, it may be rotated at slow speed from the driving-shaft 11 by clutchine the pinion 23 to the shaft 26.

After each layer of fabric has prelin1inarily been applied to the form 31. and in the c dition shown in Fig. 10. the lever 28 is operated t. l lug-age the clutch-member 27 with the gear-wheel 22, thereby rotating' the form 31 at ai'liigher rate of speed.

The hand-lever 118 is then operated to adjust the canrbloek 101 to its second position-that in which the roller 103 will tram ersc only the horizontal portion 105 of the camway 102. and in which instance the abutment 125 of the stop-block 54 will be in alinement with the slide-block The airytheoperating rod 85 is also adjusted so that it, will operate the valve-arm 74 at the some time that the slide-block imthe? they will adhere i-Ofiiliiitil anti 1o tho pinges a ainst the abutment 125.

The effect of this operation is to cause the toothed-wheels 89 L0 engage the racks 90 and move the brackets 59 on their axes formed by the pivot-studs 86 so that the angular relation of the rollers 57 to the tireform will be changed from that indicated at h to that indicated at i and j in Fig. 12, and, moreover, the rollers 57 in addition to being given a rotative movement are bodily moved from the position indicated at 71 to the position indicated at j. While these movements of the rollers 57 are being eti'ected, they are, of course, maintained against the fabric by the air-pressure in the cylinders 63 and are thereby similarly maintained while following the contour of the beads c so that they may also roll or shape the fabric over the beads. It is to be understood that the contour of the camvvay 102 Where its horizontal portion 105 joins its downwardly-extending portion 10% is such that the presser-rollers 57 are held in the corners m formed by the beads e a short period of time before the rollers continue over the beads. This operation etlccts the formation of the desired distinct corners or grooves m. It is while the rollers are held in the corners m that the corner 109 of the arm 108 is pressed against and caused to follow the roller 103; and the purpose of this arm 108 is to take the back pressure against the roller 103 in rolling the corners or grooves mi As the prcsser-rollers 57 reaci the position indicated at j in Fig. 12.

the abutment 124 and slide block 53 operate automatically to stop the carriage 35; and, at the same time, the rod 85 moves the valve arm 74 to the .dottcddine position in Fig. 23, closes the valve-inlct-opening 76, opens the valve-port 77, permits the air to escape from the cylinders 6 :3. and enables the springs (37 to draw the rollers 57 awa y from the fabric.

This done. the. carria e is iven a i'cccdin I movement which causes the shaft 93 to bc rocked to bring the roller 103 back into the horizontal portion 105 of the cannvay 102 the carriage 555 being moved back to the position shown in the drawings against the stop 1 19. These operations are continued until the desired number of layers or plies of fabric have been applied over as well as under the heads 6.

After the. final layer of fabric has been applied, the brackets 127 carrying the cutters 139 are moved into operative position and the cross-heads 129 and brackets 134 are adjusted thereon to bring the cutting edges of the knives 139 into position just inwardly of the heads (1 and Where it is de sired to sever the rough. intardly-projecting edges of the fabric. The levers 141 are then forced by hand toward the rotating tire-form 31, causing the cutting edges of the knives 139 to sever the rough edges of the fabric. The carcass than complete and may then be removed from the form 31 in the usual. manner.

Difi'ercnt sized tirc-forins or cores may, of course, be applied to the core supporting structure. aforementioned. for th production of carcasses of different sacs; and various parts of the machine may bk adjusted so that the operations hereinbetore described may take place with respect to the forms of ditlcrent sizes, and, for this pui pose in addition to those previously retirred to, the following adjustments may be made: The general position of the cam-block 01. may be adjusted by a screw 152 when e stud H5) is adjusted in the slot 114, the scww 1:32 being.threaded through a block 153 v21 the bracket 3;? and forming an abutment the outer end of the cam-block 101; the 525 may be adjusted on the. rib 33 of the bracket 32 to adjust the position of the stepblock 54- and be held in position by its set screw .56: the collar 81 may be adjusted on the rod 79 and held in place by its set-screw; and the rod ma be longitudinally ad iustcd on the csrri 1 and. held in place by its set-screzv.

To facilitate the setting of the cam-block 101 accurately with respect to forms of different sizes, the top of the plate or rib 113-- may be provided with an indication-plate 155 having appropriate marks thereon corltFpiiiltling with iilif-fOI'HlS of diltercnt sizes: and the tiliil blUCli 101 may be providcti with an indicator-arm 156 projecting over the marks on the plate 155 and adapted to move over the same to indicate the cor- .vw'l positions for the cam-block 101 when it is. adjusted. The indicator-plate 155 is also adjustable by means of a screw 157 and is held in position by a se -screw 158.

From the. foregoing, it Will be perceived that l have devised a tire-making machine which is well adapted to achieve the several objects and ends in View. The structure, as a whole, is exceedingly simple and compact in form, it capable of producing carcass-cs with great rapidity, and the product thus produced is of superior grade in that the successive plies of fabric are superposed one upon the other evenly and uniformly; each carriiss is uniform with others; and ditlcrcnt of tires can be formed upon the same machine. As many changes can be made in the construction and many widely diflcrent embodiments of the invention can obviously be made without departing from its spirit. it is intended that all matter contained in the foregoing description and shown in the accompanying: drawings shall be iiitcrprc =d as illustrative and not in a limiting scn. licncc the language employed in the following claims is intended to cover all of the generic and specific features of the invention.
